Things I liked: Perfect fit for my brand new Hatsan 125TH. Bought this to replace a defective factory seal, and the performance now exceeds factory specs. I bought my brother the same gun, and it's velocity is deteriorating just like mine. I'll be getting another one of these and replacing the factory seal on his gun as well.

Things I would have changed: It would be nice if Hatsan had better quality control so bad seals were not installed on the pistons.

What others should know: This seal change requires tearing down the entire gun. This is NOT your simple DIY project, and requires extensive knowledge and tools most people do not have. Know what you are getting into before attempting this project!

Things I liked: Fit perfect and seems tough Tuned my gun to a much more accurate shooter. It say's to be installed by a professional. Well I guess the factory should try that and it wouldn't need replacing.

Things I would have changed: Nothing worked fine

What others should know: Check your gun, this will improve accuracy a lot.

Things I liked: Good quality material

Things I would have changed: nothing

What others should know: Perfect for Hatsan 125 series. The factory seal blew at about 200 shots on mine and when I pulled the piston it seemed to be undersized a tad. This one fits tighter. I soaked it in warm water for a few minutes and it popped right on, no tools used

  • Fred Necke from USA asked:

    I have opened my Hatsan 125 and it seems as if the seal is rock hard. It was very difficult to cock and firing was 'erratic'. The piston was very tight in the chamber and I had to use a hammer to ease it out. But I cannot see any metal on metal chaffing marks. If the rifle was left in the direct sun could the seal have become rock hard?

    • Chevota from USA:

      The sun/heat no doubt dries and hardens a seal sooner, but my guess is that would take a looong time. The oem seal is just low quality. My oem Hatsan seals, including 125, are no doubt the hardest seals I've ever removed from a gun. I have a used 125 seal and this new red one in my hands as I write this, and while the red seal is a hard for an aftermarket, it's much softer than the oem. Plus it's a better material so I'd bet $ it'll still be softer after 20 years. Seems like polyurethane to me but who knows. Note the damage to the oem seal caused by the sharp edges in the tube cutouts. Smooth those before installing this new seal!

  • jim from Malta asked:

    Is this seal fits gamo hunter 1250

    • Chevota from USA:

      The 125 seal fits the Trail XL, and since the 1250 and XL are very much the same I'd assume yes. The OD of this seal (new) on the top/bottom is ~1.145"/1.105, and ID ~.614"/.578". An oem XL seal (new) is ~1.165/1.040 ~.660/.520. Thickness of each is ~.260". So the dimensions looks like it's a no-go, and the Walther seal is not actually tapered on the inside, but stepped, yet it works perfectly on the tapered dovetail of the XL. So my guess is if your dovetail is ~.630" wide and ~.230" tall, I'd say yes... If your dove is much wider, like .750", then I'm betting the NP2 seal (CRS5177-012) will fit.

  • Chris from USA asked:

    Is this the proper seal for a Walther FH with Crosman nitro piston?

    • Chevota from USA:

      Yes, the seal fit the Walther FH regardless of what spring you have.
